Boil the peeled and quartered potatos until soft, meanwhile bake the sausages in the oven at gas mark 5 / 190C / 375F, turning after 12 minutes.

The potatos should be done after 20 mins. Drain and add enough butter and milk to make a creamy mash. Season gently

Check the sausages after 25 mins total, they should be done.

Heat the beans in a pan, then layer in the bottom of a casserole dish. Cut the sausages into chunks and layer over the beans then spread the mash on top. Older kids may prefer the sausages poked upright through the top of the mash rather than cut up.

If you wish you can put it under the grill to crisp the potato, or sprinkle cheese on top. My kids like theirs in individual dishes so they have their own 'pies'
